KVM-Guests can't get past bridge - no internet connection
- by tmn29a
I'm running a backported KVM on a Debian Squeeze. ATM the KVM-Guest can't connect to the internet through the bridge I have set up. The guests can reach each other, the host but nothing outside. I can neither ping, nslookup or do anything to a remote address. The guest are configured to have a static IP. When I didn;t have the bridge but a virtual bridge (the KVM-default) the guest could connect fine. After setting up the bridge things broke, so I think the problem lies there.
